I shoot a lot of trap (18,000 rounds so far this year) I reloaded about 2/3 of them but will buy any brand of shell I can find that are 1 oz or 1 1/8" oz #8 at speeds of 1150 to 1290 fps if the box is $4 or less. I've found that Federal Top Guns, Estate, Gun Clubs, Remington and Win. Sport loads work great from the 16yd line back to the 24. At $4 a box the cost come close to my reloads using quality components. I'll shoot my reloads for most registered shoots but find the above loads work just as well in most cases. With lead pushing $50 a bag, $4/box looks darn good vs. almost $7 a box for the good stuff like AA and STS.
Buy a box and try them out, use a couple of different chokes to see which pattern the best. I'm seeing more and more good shooters using these loads for their 16 yard programs.
